technical field

The utility model relates to the technical field of wastewater treatment, in particular to an industrial wastewater treatment device of granular activated carbon.

Background technique

Granular activated carbon is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke. Granular activated carbon has developed pore structure, large specific surface area, abundant surface chemical groups, and specific adsorption. It has the advantages of strong ability and high physical adsorption and chemical adsorption for most common organic pollutants and heavy metal ions. Therefore, granular activated carbon is often used in industrial wastewater treatment.

However, when the commonly used industrial wastewater treatment device of granular activated carbon is in use, the activated carbon particles arranged inside are usually in a static state. In the process of purifying the wastewater, the contact between the activated carbon particles and the wastewater is not sufficient and comprehensive. The treatment effect is not ideal, and in the process of wastewater treatment, when the activated carbon particles need to be replaced, it is necessary to suspend the transportation of wastewater to the inside of the treatment device and suspend the operation of the treatment device before the activated carbon particles can be replaced.
